FINANCIAL STATEMENT:
~.~Review information in the report and approve the recommended
priorities, or provide direction to Staff regarding any changes in the
undergrounding priorities
The City has a balance of approximately $115,000 in its Public
Utilities Commission (P.U.C.) Rule 20A account as of Fiscal Year
2003-2004 and will accrue additional funds at a rate of about
$125,000 per year. It is possible to "borrow out" funds three years
in advance; thus, the available funding at the beginning of Fiscal
Year 2005-2006, including "borrowed" funds would be $865,000.
FY 2005-2006 is the earliest the City could undertake the next
district due to design times and PG&E lead time.
DESCRIPTION: In January 1999, the City Council approved a list of potential street
segments for future utilities undergrounding. The current Priority List is shown below:

1. Dublin Blvd. 600' West of Clark Avenue to Sierra Court 1,600

ITEM NO.
The first priority segment, which is Dublin Boulevard from 600' west of Clark Avenue to Sierra Court,
was recently completed in conjunction with the Dublin Boulevard Widening project.
Undergrounding of the utilities on Dougherty Road from Dublin Boulevard to the Southern pacific
Railroad is currently listed as the fifth priority segment. The widening of Dougherty Road from 1-580 to
Houston Place, including the intersection improvements at Dougherty Road and Dublin Boulevard, is
tentatively scheduled for construction during Fiscal Year 2005-2006. Preliminary design and
environmental analysis for the project are currently underway. It is preferable to install the joint trench
and underground the overhead utilities prior to completion of the construction of the Dougherty Road
widening. In addition to the benefit of "cleaning up" an area by widening the roadway and
undergrounding the utilities, PG&E allows an undergrounding funding credit equal to the cost that would
have had to be borne by PG&E for moving the poles back from the roadway for the widening.
Based on information provided by PG&E for the available funding balance in the Rule 20A allocation and
the projected annual accumulation and allowable "borrow out" provisions, it is estimated that a total
amount of $865,000 will be available at the beginning of Fiscal Year 2005-2006 from Rule 20A funding.
The estimated cost of undergrounding the facilities is $561,000.
The City would need to install street lights where gaps in the street light pattern would result due to the
removal of existing lights on wood poles. Rule 20A fimds do not cover the installation of street lighting.
For the Dougherty Road segment, eight street lights will be included in the project scope of the Capital
Improvement Project, the cost of which is estimated at approximately $50,000. The cost to underground
private services to commercial buildings that are .served overhead at the time undergrounding takes place
is an expense that is typically required to be borne by the private property owners, However, all of the
existing properties fronting the segments to be undergrounded already have Underground services to the
buildings. Hence, there will be no cost to the property owners due to undergrounding of the overhead
service lines along the street frontages.
Staff is recommending that the priority list for the undergrounding projects be revised to remove the
Dublin Boulevard segment 1 that has been completed, and move the Dublin Boulevard and Dougherty
Road segments 5(a) and 5(b) from priority number 5 to priority number 1. Segment 5(c), Dougherty
Road from Sierra Lane to the SPRR, is proposed to be moved to priority number 6 as shown below in the
revised recommended Priority List.
Staff is also recommending that the Scarlett Court be moved from the current priority number 10 to
priority number 2 due to its close proximity to the 1-58.0/Dougherty Road interchange, which serves as a
major entrance to the City. Scarlett Court will be broken into two segments: 2(a) from Scarlett Drive to
the east end and 2(b) from Dublin Boulevard to Scarlett Drive.
The priority order of the remainder of the projects on the list would remain unchanged.
The revised recommended Priority List, based on the Dublin Boulevard / Dougherty Road intersection
being the next large Project, is shown below:

the
ADOPTED POLICY REGARDING PRIOR/T/ES
FOR TIqE UNDERGROUN~DING OF EXISTING OVERHEAD UTILITIES
(June 13, 1983)
Commercially fronted streets considered before residential fronted streets because of higher visibility due
to commercial setbacks and higher traffic volumes thus affecting more people.
Streets with pole lines on two sides of the street be considered before streets with poles on one side of
street due to the greater reduction in visual pollution.
Consideration be given to projects including outside participation such as private developers or assessment
districts which would considerably lessen the public cost of the project.
Consideration be made where a street is to be widened 'and the existing overhead utilities will need to be
.relocated.
Review of priorities be made on an annual basis or more often as circumstances warrant.
RECOMMENDED PRIORITIES
Commercial Areas
More visibility, high traffic use
A. 'San Ramon Road - Dublin Blvd. to Martin Canyon Creek (Poles both sides of street and
can match timing with widening of roadway). Rule 20A estimated cost $350,000 (total
cost with street lights $400,000).
B. Dublin Blvd. - San Ramon Road to Golden Gate Drive (poles on both of street and heavy
downtown traffic). Rule 20A estimated cost $421,000 (total cost with street lights
$~63,000).
C: Dublin Blvd. - Golden Gate Drive to 1-680 (poles both sides of street). Rule 20A estimated
cost $336,000 (total cost with street lights $372,000).

E. Dublin Blvd. - San Ramon Road to Silve~ate Drive
F. Dublin Court
G. Dougherty Road
H. Village Parkway - Dublin Blvd. to Amador Valley Blvd. (note that existing overhead lines
are already on street light poles).
